Sigurd's mission was not yet accomplished; so on he rode to King Giuki's hall, king of Frankland, whose queen was Grimhildr, who had two sons named Gunnar and Hogni, and a step-son called Guttorm, and whose daughter was the lovely Gudrun. Sigurd, greatly attached to his lovely bride at the lone fell, purposed going back for her; but Grimhildr, who was skilled in the black arts, longed for the brave Volsung for her own daughter, and therefore prepared for him the philter of forgetfulness. He quaffed it off, forgot Brynhildr, fraternised with Gunnar and Hogni, and married Gudrun. Giuki now wanted a wife for Gunnar, and the brothers with their bosom friend set out to woo. They chose Brynhildr, whom they found still sitting on the fell, waiting for Sigurd to come back. She had made it known, that whoever could pass that flame should have her for his wife; so, when Gunnar and Hogni reached the spot, the former rode at the flame, but his horse swerved from the fierce fire; then, by Grimhildr's magic arts, Sigurd and Gunnar changed shapes and arms, and Sigurd mounted Gran, and the noble steed carried him through the flame. Thus Brynhildr was wooed and compelled to yield. That evening they were united in wedlock; but when they retired to rest Sigurd unsheathed Gram, and laid it between them. Next morning, when he arose, he took the ring which Andvari had laid under a curse, and which was among Fafnir's treasures, and gave it to Brynhildr as a gift, and she gave him another ring in return. Then Sigurd returned to his companions in his own shape; and Gunnar went and claimed Brynhildr as his bride, and carried her home. No sooner was Gunnar wedded than the power of the philter ceased to operate: he remembered all that had passed, and the oath he had sworn to the fair Brynhildr. When she discovered that she had been deceived, she engaged Gunnar to revenge her wrong. By charms and prayers the two brothers set on Guttorm, their half-brother, to take vengeance, and the hero was pierced through with a sword while he lay in Gudrun's white arms. Though Sigurd turned and writhed in agony, he had strength left to hurl Gram after the treacherous Guttorm as he fled. The keen blade cut him asunder, and his head rolled out of the room. Brynhildr's love returned; and when Sigurd, who expired of his wound, was laid upon the pile, her heart broke. She in song predicted woes that were to come, made them lay her side by side with Sigurd, with Gram between them, and so went to Valhalla with her old lover. Andvari's curse was thus fulfilled.
